Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (31.6 Ohms), tolerance (±1%), power rating (0.25W), package format (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and regulatory compliance (RoHS3). All substitute parts listed meet these core electrical and mechanical requirements.

Substitute parts are categorized into two groups:

Direct Substitutes maintain identical specifications to the main part with no additional features or certifications. These parts are interchangeable without design modification.

Similar Substitutes meet all core electrical and mechanical parameters but include additional certifications or features such as AEC-Q200 automotive qualification. These parts are compatible but may have different application scope or product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

For General Industrial Applications: CR1206-FX-31R6ELF (Bourns Inc.) or RC1206FR-0731R6L (YAGEO) are direct substitutes with Active product status. Both maintain identical electrical specifications and RoHS3 compliance. Selection between these two is based on inventory availability and packaging preference.

For Automotive Applications: CRCW120631R6FKEA (Vishay Dale) is the appropriate selection when AEC-Q200 automotive qualification is required. This part meets all core electrical parameters while providing automotive-grade certification. Product status is Active.

For Legacy Design Continuation: ERJ-8ENF31R6V (Panasonic Electronic Components) meets all electrical and mechanical requirements but carries "Not For New Designs" product status. This part is suitable only for sustaining production of existing designs and should not be selected for new product development.

Inventory Considerations: CR1206-FX-31R6ELF (Bourns) offers the highest inventory availability at 15,888 pieces, followed by CRCW120631R6FKEA (Vishay Dale) at 7,866 pieces and RC1206FR-0731R6L (YAGEO) at 7,472 pieces.

Frequently Asked Questions (FAQ)

Q: Can RC1206FR-0731R6L (YAGEO) be used as a direct replacement for RC3216F31R6CS (Samsung)?

A: Yes. Both parts share identical electrical specifications (31.6 Ohms ±1%, 0.25W), package format (1206), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and RoHS3 compliance. Physical dimensions are within acceptable tolerance for PCB footprint compatibility.

Q: What is the difference between CR1206-FX-31R6ELF and CRCW120631R6FKEA?

A: Both parts meet core electrical specifications. The primary difference is that CRCW120631R6FKEA includes AEC-Q200 automotive qualification, making it suitable for automotive applications. CR1206-FX-31R6ELF does not carry automotive certification. Selection depends on application requirements.

Q: Why is ERJ-8ENF31R6V marked "Not For New Designs"?

A: This designation indicates the part is in the later stages of its product lifecycle. While it meets all electrical and mechanical specifications and is suitable for sustaining existing production, it should not be selected for new product development. Use CR1206-FX-31R6ELF, RC1206FR-0731R6L, or CRCW120631R6FKEA for new designs.

Q: Are all substitute parts available in Tape & Reel packaging?

A: CR1206-FX-31R6ELF, RC1206FR-0731R6L, CRCW120631R6FKEA, and ERJ-8ENF31R6V are all available in Tape & Reel (TR) packaging format. Packaging format is consistent across all listed substitutes.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All substitute parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life under normal storage conditions without special moisture control requirements.

Q: Can CRCW120631R6FKEA be used in non-automotive applications?

A: Yes. CRCW120631R6FKEA meets all electrical and mechanical specifications required for general industrial applications. AEC-Q200 certification is an additional qualification that does not restrict use in non-automotive circuits. This part is suitable for any application requiring a 31.6 Ohm ±1% 0.25W 1206 resistor.
